PURPOSE The purpose of this study was to investigate the clinical outcomes of bromfenac ophthalmic solution 0.09% once daily (QD) and nepafenac 0.1% ophthalmic suspension three times daily following cataract extraction with posterior chamber intraocular lens implantation, specifically looking at any differences in Early Treatment Diabetic Retinopathy Study visual acuities, macular volume, and/o...

Dendritic Ag2Se nanostructures are synthesized in a dry environment by UV irradiating the hybrids composed of CdSe quantum dots (QDs) and silver (Ag). UV irradiation on CdSe QDs induces a photooxidation effect on the QD surface and leads to the formation of SeO2 components. Then SeO2 reacts with the Ag atoms in either Ag film or QD layer to produce the Ag2Se. The growth mechanism of Ag2Se dendr...

Physics-based numerical simulations of earthquakes and slow slip, coupled with field observations and laboratory experiments, can, in principle, be used to determine fault properties and potential fault behaviors. Because of the computational cost of simulating inertial wave-mediated effects, their representation is often simplified. The quasi-dynamic (QD) approach approximately accounts for in...

We have investigated the quantum dot (QD) carrier capture mechanism using continuous wave photoluminescence as a function of the optical excitation intensity using a sample with a QD density gradient across its surface ranging from 0 to 1.8 £ 10 cm. Modelling of the carrier kinetics has been described by a set of three coupled rate equations associated with the carrier population in the GaAs ba...

In this work Silvaco TCAD have been used to model quantum dot solar cell. It was found that the addition of InAs QD(quantum dot) in the intrinsic layer of hetero-structure InGaP/GaAs p-i-n solar cell extends the absorption range of the solar cell, thereby giving rise to efficiency enhancement of the QD solar cell by 3.8851 % it was also observed that the fill factor increases from 83.2724% to 8...

A complete semi-analytical model is proposed for the simulation of the electronic, mechanical and piezoelectric properties of narrow gap strained semiconductor quantum nanostructures. A transverse isotropic approximation for the strain and a new axial approximation for the strained 8x8 Hamiltonian are proposed. It is applied extensively to the case of InAs/InP quantum dots (QD). Symmetry analys...

The generalized Fibonacci cube Qd(f) is the graph obtained from the d-cube Qd by removing all vertices that contain a given binary word f as a factor; the generalized Lucas cube Qd( ↽Ð f ) is obtained from Qd by removing all the vertices that have a circulation containing f as a factor. In this paper the Wiener index of Qd(1) and the Wiener index of Qd( ↽Ð 1) are expressed as functions of the o...

We report the experimental observation of photon antibunching in the photoluminescence of a chemically synthesized CdSe/ZnS quantum dot (QD) at room temperature and from a single selfassembled InAs/GaAs QD at 4 K. These results prove that a single quantum dot acts like an artificial atom, with a discrete anharmonic spectrum. Using the quantum regression theorem, we find that the normalized seco...

Recent experiments have explored the response of a single modeoptically injected QD laser. The experiments identify a domain ofbistability between two steady states at negative detuning and a Hopfbifurcation close to the locking threshold at positive detuning. More-over, the laser is stable for all injection levels at zero detuning. Theseobservations lead to a stability ...

UNLABELLED To date, the in vivo imaging of quantum dots (QDs) has been mostly qualitative or semiquantitative. The development of a dual-function PET/near-infrared fluorescence (NIRF) probe can allow for accurate assessment of the pharmacokinetics and tumor-targeting efficacy of QDs. METHODS A QD with an amine-functionalized surface was modified with RGD peptides and 1,4,7,10-tetraazacyclodoc...
